Re: [flexcoders] Please share your experiences with Flex 3 charting (visualization component)
Yes it looks pretty stable. Thanks for sharing it. I'll re-visit my stuff and share my findings.

I think the problem lies in your dynamicly creating the columseries, for my sample, dynamic created data for a fixed number of lineseriese chart running all day long does not see any memory leak. sample file attached -- lwz7512 Ultrapower Flex Team Leader www.ultrapower.com.cn - Original Message From: Maciek Sakrejda <[EMAIL PROTECTED]> To: flexcoders@yahoogroups.com Sent: Thursday, September 18, 2008 1:29:19 AM Subject: Re: [flexcoders] Please share your experiences with Flex 3 charting (visualization component) We use Flex for a real-time dashboard at Truviso, and we haven't run into any major with charts so far.

Re: [flexcoders] Please share your experiences with Flex 3 charting (visualization component)
We use Flex for a real-time dashboard at Truviso, and we haven't run into any major with charts so far. For what it's worth, we're still on Flex 2, but with FB3, which the bug report states *should* reproduce the problem (which is odd--FB itself should have nothing to do with this if the SDK versions are identical). I also noticed from the bug description that this happens mostly when replacing the dataProvider/series: we keep the same series/ListCollectionView object but update the contents as new data comes in. We definitely depend on Flex Charting for a stable real-time dashboard, and the data binding paradigm makes this an ideal library for this purpose.
